Question

        ObjectMetadata metadata = new ObjectMetadata();

        metadata.setContentEncoding("gzip");
        metadata.setContentType("application/x-gzip");
        metadata.addUserMetadata("Expires","3600");
        metadata.addUserMetadata("Cache-Control","public");
        metadata.addUserMetadata("max-age","432000");

我在s3中获得了关键词“x-amz-meta-max-age”，“x-amz-meta-expires”。它的补充 “x-amz-”在前面请帮忙但是setContentEncoding，setContentType工作正常但是休息3在前面得到“x-amz-”请帮忙

您可以设置：

metadata.setExpirationTime("Thu, 21 Mar 2042 08:16:32 GMT");
metadata.setCacheControl("public");
